HOOK.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed January 10, 1910. Serial No. 537,285.

To all whom it may concern:

Be it known that I, J OSEPH Dovo, a citizen of the United States,residing at Tenino, in the county of Thurston and State of Washington,have invented a new and useful Hook, of which the following is aspecification.

This invention relates to hooks and especially to that kind known asbutt hooks for use on the end of a cable used in logging and similarindustries and has for its object to provide a hook which shall besimple and strong in construction and which has its throat closed by alatch which will prevent the object which is grasped by the hook fromescaping therefrom.

With the above object in View, the hook consists of a shank having abill formed at one end thereof and a slot provided in the tip end of thebill. The latch is pivotally attached to the shank in the vicinity ofthe end thereof opposite the end provided with the bill and the free endportion of the said latch is slit or bifurcated and is adapted to haveresilient or frictional contact with the sides of the slot in the billwhen the latch is closed whereby the said latch is effectually held inclosed position across the throat of the hook. In one form of theinvention, the hook is provided with a swivel of especial arrangement aswill hereinafter appear.

In the accompanying drawings: Figure 1 is a side elevation of one formof the hook. Fig. 2 is an edge elevation of the same. Fig. 3 is a sideelevation of another form of the hook showing the latch in closedposition. Fig. 4 is a side elevation of that form of the hook shown inFig. 3 illustrating the latch in open position. Fig. 5 is an edgeelevation of the form of hook shown in Fig. 8, showing the latch closed.

The hook consists ofa shank 1, one end of which is formed into a bill 2having at its extremity a transversely disposed slot 8. Spaced ears 4are formed at the end of the shank 1 other than the end formed into thebill 2 and a latch 5 is pivoted between the ears 4:. The said latch maybe in the form of a bar as shown in Figs. 1 and 2 or in the form of asector as illustrated in Figs. 3, 4, and 5. In both instances, the latchis pro vided with a bifurcated free end 6, which when the latch isclosed, is adapted to be sprung into engagement with the sides of theslot 3 provided at the end of the bill 2. As above stated, the free endof the said latch may be bifurcated or slit and the free end portions ofthe said latch are comparatively resilient when considered with relation to the body or pivoted portion of the said latch.

As illustrated in Figs. 3, 4, and 5 of the drawings, the shank l isprovided with a perforation 7 by means of which it may be attached to acable in any appropriate manner. In the form of the invention asillustrated in Figs. 1 and 2 of the drawings, an eye 8 is swiveled in anenlargement 9 formed at one end portion of the shank 1 and the said eyeis retained in position with relation to the shank by means of a head 10formed at its end located within the hook proper. In this form of theinvention, it is understood that the cable is attached to the eye in anappropriate manner.

From the above description, it will be understood that when the latch ismoved to a closed position across the throat of the hook, the bifurcatedor slit end of the said latch will engage the side walls of the slots 3and will thereby be held in closed position and in order to open thesame it will require a strong lateral pull.

The advantage gained by applying the swiveled eye 8 to the form of hookas illustrated in Figs. 1 and 2 of the drawings may be explained bystating that in logging districts where machinery and wire rope are usedfor handling logs, the hook and swivel have generally been separatedbecause the lines on the swivel would become unfastened from the hookand by reason of the fact that in the present assemblage the head of theswivel is located within the shank of the hook, the latch will protectthe end of the swivel against outer obstructions when the said latch isclosed.

When the hook is in use and the latch is closed, there is no excessivestrain upon the latch, the only strain being the slight weight of aslack cable or rope when the same is being shifted and therefore it isnot necessary to have a latch of great strength in order to hold thecable or line in the hook.

Having described the invention, what I claim as new and desire to secureby Letters Patent is:

1. A hook comprising a shank having one end portion adapted to beconnected with a cable and its other end portion formed into a billhaving a transversely disposed slot, a latch pivoted to the shank andhaving a free end portion adapted to enter the slot at the 1 bill of theshank and to spring laterally into eiigagement with the side Walls ofthe said s 0t.

2. A hook comprising a shank having one end portion formed into a billprovided With a transversely disposed slotted extremity, a latch pivotedto the shank and having a bifurcated end adapted to enter the slot atthe bill end of the shank and to spring into engagement With the sideWalls of the said slot, an eye sWiveled to the other end portion of thesaid shank and havin an en larged end located Within the said s ank.

I In testimony that I claim the foregoing as 15 my own, I have heretoafiixed my signature in the presence of two Witnesses.
